TRACK-CLEANER.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed October 11, 1906. gerial No. 338,400.

To all whom it may concern:

Be it known that I, DANIEL R. EDWARDS, who am a citizen of the United States, residing at Orange, county of Orange, State of Texas,'have invented a certain new and useful Improvement in Track-Cleaners and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to track cleaners for sawmill carriages, and has for its object a simple and eflicient member, whose cost is very slight, whereby the sawdust, as it falls from the log that is being cut, is kept from falling upon and gradually clogging the track under the carriage.

In the drawings :Figure 1, is a perspective of the frame and shoe on a section of track. Fig. 2, is a plan view from beneath of the shoe member. Fig. 3, is an elevation of the same.

1 represents a frame adapted to be attached to the sawmill carriage by bolts 2 passing through suitable holes. Its lower end is vertically telescoped, and into it extends the complementary slide 3, which projects from the upper surface of the carriage shoe 4. This slide is preferably square or elliptical in cross section, so that any tendency of the shoe 4 to turn about from its proper extent along the track 5 is prevented. The line of reciprocation of the carriage is of course exactly parallel with the track.

The shoe is, in its ground plan, a trapezoid, whose most desirable extent along the track I find to be about nine inches on the log deck side, and seven inches on the other side. Being about three or four inches wide it extends completely over the track, and somewhat on each side. As shown in Fig. 2, the end or track-engaging face of the shoe is divided into three compartments or sections by ribs a. blocks 6 are driven, so as to project below the lowermost edge of the metallic shoe and engage directly against the track 5. These blocks alternate with exposed portions of Babbitt metal. of the shoe and of the blocks at the ends oper- Into each of these hardwood The obliquity of each end ates to clear off from the track and throw to one side the accumulated sawdust, rather than merely push it to the end of its possible travel on the track. The blocks, both metal and wood, may be renewed as desired, though I find the combination is one that lasts a long time.

Along the rear face of the frame extends a horizontal rib 6, which is designed to'fit closely within a complementary groove in the side of the carriage frame. Its purpose is to relieve the bolts 2, by which the depending frame is attached to the carriage, of some of the twisting strain which the sliding of the cleaner along the track would otherwise impose upon them.

WVhat I claim is 1- 1. A track cleaner having in combination with a depending frame piece adapted to be attached to a moving carriage, a shoe member connected therewith and adap'ted'to be moved along its supporting track thereby, said shoe member having on its under face a plurality of compartments spaced from'one another by metal ribs, and a plurality of wearing blocks held therein and adapted to engage directly against the track.

2. In combination with a frame piece adapted to be attached to a movable oarriage, the upper portion of said piece being provided with a groove adapted to engage over a complementary rib on said carriage, a shoe member engaged by said frame piece, and a plurality of wearing blocks driven into the under face of said member, substantially as described.

3. In combination with a plurality of wearing blocks adapted to engage over a sawmill track, a shoe wherein said members engage, both said shoe and said wearing members being oblique to the track at the outer ends, and a frame piece whereinto said shoe telescopes, adapted to be attached to the movable portion of the sawmill carriage, substantially as described.

In testimony whereof, I, sign this specification in the presence of two witnesses.
